STOP-VALVE FOR WATER-=SERVICE PIPES.

SPECIFICATION forming part of Letters Patent No. 364,018, dated May 31,1887.

Application filed December 13, 1886. Serial No. 221,390; (No model.)

To all whom it may concern:

Be it known that I, DANIEL KEARNEY, of Montreal, District of Montreal,Province of Quebec, Dominion of Canada, have invented a new and usefulImprovement in StopValves for \Vater-Service Pipes, of which thefollowing is a specification.

The stop-valves or stopcocks of servicepipes have heretofore usuallybeen operated by means of a rod passed down to the valves through a tubeor casing. The'stop-valves are in such cases buried several feet deep inthe ground, and the said tubes or casings extend therefrom to thesurface of the sidewalk or pavement, above which they frequently projectsufficiently to form an annoying obstruction to travel. Owing tooxidation or displacement of the iron casing, repair is often necessary,and this necessitates digging up a portion of the sidewalk or pavement.In replacing the earth and surface-covering-such as stone, brick, orcement, &'c.-re|noved in this operation, an unequal settling occurs andthe surface nevertagain assumes its former evenness or regularity ofappearance.

The above defects have led me to my present invention, by which suchstop-valves may be operated from within the basement or cellar of thebuilding which the service-pipe enters. In practice I attach a piston tothe stopvalve and move the latter up or down (to let on or shut offwater from the building) by forcing air or other gas or fluid into thepiston-chamber. The piston-cylinder is provided with two pi pes,whichextend into the basement or cellar or beyond, so that their free endsare always easily accessible, and through these pipes the fluid isforced and conveyed to the piston-cylinder. The free ends of the pipesare open'and so constructed as to adapt them for detachable connectionwith a portable forcing apparatus.

The invention will first be described generally, and the particularconstruction and combination of parts constituting the novel features ofmy invention specifically indicated in the claim.

In the accompanying drawings, Figure 1 is a sectional view showing thearrangement of parts asI propose in connection with the basement of abuilding. Fig. 2 is a vertical sec- 'up, and thus closed or opened atwill.

tion of the stationary apparatus I employ. Figs. 3 and 4 are sectionalviewsillustratlng the operation of the forcing device in shifting thestop-valve.

The stop-valve 1 works in a cylinder, A, having lateral branches at a,one, a, of which is adapted for connection with the supply-pipe B,leading to the main, (not shown,) and the other, a, for attachment ofthe service-pipe 0, leading into the building to which water 1s to beadmitted. The passage of water into the servicepipe 0 will obviously beadmitted or cut-off, according as the valve 1 is raised from or closedon its seat, as respectively represented in Figs. 3 and et. The valve ispro vided with a stem, 2, to whose upper portion is affixed a piston, 3,that works in a chamber, A, forming the detachable upper portion orextension of the cylinder A. The piston 3 fits snugly'in said chamber A,and its stem 2 works through a stuffing-box, 4. It will be readily seenthat by forcing any fluid-say air-into the chamber A above or below thepiston.3, the valve 1 may be shifted down pr 0 provide for thisoperation, two pipes, D D, extend horizontally from the piston-chamber Athrough the basem'entwall E of the building. One, D, of these pipesconnects with the chamber A above the piston 3, and the other, D, belowit. Their'free ends a terminate within the basement or cellar of thebuilding, where they are always readily accessible. Such ends are leftopen and made flaring or funnel-shaped, as shown, to adapt them fordetachable coupling or connection with a portable forcing apparatus, 5.The latter is in the form of a force-pump or large syringe having asliding piston, and its nozzle b is tapered, corresponding to the flareof the ends a'of pipes D D, so that when said nozzle is inserted thereinit will fittightly and prevent escape of the air or other fluid employed.

It will be apparent from inspection of Fig. 3 that when the forcingdevice or apparatus 5 is applied to the pipe D, and the piston of thesame forced in, the fluid contained in it will be forced into thechamber A above, the piston 3, and the latter forced down, thus closingthe valve 1 on its seat, as shown in Fig. .4,

water to the service-pipe C. When the valve 1 is open or shut, thepressure of water in the cylinder A holds itin that position until againmoved by superior pressure of fluid on the piston 3, as beforedescribed.

By my invention, the stop-valve being placed under control from withinthe building, the use of the aforementioned objectionable rod, casing,or tube in the sidewalk or street is avoided. V

The forcing device 5 is kept in possession of the municipal authoritieshaving charge of the water-works, so that the admission of water to thebuilding is always under their control. 7

To further define the novelty of my invention, I will state that thevalves of flushing pipes for water-closets have been operated bypressure of water acting on pistons connected with them; but theadmission of water to the piston-chamber was controlled by a twowaycock, located above or contiguous to the closet-seat and accessible toany one using the closet. The available pressure of water was alsodependent on the head in the supply or service pipe connected with thepipes lead-. ing to the piston-chamber; and in case the piston or valveshould stick the pressure of water on the former could not, therefore,be increased, and hence a failure to operate would be the result. Myinvention is distinguished from that, first, bya difference of purposeor object; second, a difference of location of parts; third, adifference of construction and combination of parts; fourth, by the factthat the pressure on the piston may be varied as required to overcomethe stick orresistance of the valve or piston, orboth; and sixth, by thedetachable connection of the forcing device with the pipes leading tothe pistonchamber, so that the water'supply is kept within the controlof the proper authorities.

I wish it to be understood that I am well aware that operating awater-valve through the medium of a fluid forced through pipes by meansof a piston working in a fixed chamber placed in an accessible locationmore or less remote from said valve is not new, and I do not broadlyclaim the. combination of such parts; but,

Having thus described my invention, what 1 I claim as new isThe'combination of the portable forcing device 5, having a taperednozzle, b,with a valve and piston and chambers therefor, the supply andservice pipes, and two pipes, D D, leading fromthe piston-chamber andhaving their free open ends a constructed flaring or funneL shaped toadapt them for detachable connection with the said forcing device, asshown and described.
